[visualization-api] Re: Webpage with 15 graphs takes too long to load

[Nigel Griffiths]

Wow thanks for the advice.
Pretty sure I only load the chart library once.
 
The attached is a complete small example with just 30 data points per graph 
(14 of them) - which displays in 3 seconds but typically I have 300+ data 
points per graph which takes just 14 seconds but feels s ol o  n   g.
The data is embedded in the webpage to KISS - as these are generated.
I think my problem is purely size, I have 14 x 300 = 4200 data point - so I 
am asking for a lot processing.
Hence getting the first chart to display and then continuing to generate 
the other charts would make the page look responsive.
Phase two would be getting the data from a web database.

I will look into the OnClick option.

Thanks again, Nigel

[visualization-api] Webpage with 15 graphs takes too long to load

[Nigel Griffiths]

HI,
I want to display at least 15 related graphs on one web page.
- these are UNIX performance stats for on VM for a day based on nmon data.
- 1 to 4 stats with 100 to 700 data points per graph
But I find the whole pages is blank until all the graphs are generated 
which takes 12 seconds to load = which too long.

Is there a way to force the first graph to display ASAP - this gives the 
user eye candy, while the rest of the graphs are generated.

Alternative a way to use OnClick on a button to get one of the graphs drawn 
at a time each in the same screen area.
- I tried but failed to get that working using .visable and .display.

Any hints/tips would be good, Cheers Nigel Griffiths.
